Icy morning likely as freezing drizzle works in overnight

Remaining Ad Time Ad - 00:00

ROCKFORD (WREX) — Roads and sidewalks will likely be slick Wednesday morning as another storm system brings freezing drizzle to the area. The rain should hang around long enough to cause a glaze of ice this time.

Winter Weather Advisories for freezing drizzle and icy roads are in effect from 4 am to noon Wednesday (1/15/2020)

The National Weather Service issued a Winter Weather Advisory for all of the Stateline. This highlights where icy roads and sidewalks are likely. The Advisory is in effect from 4 am to noon Wednesday, giving you a window for when to expect icy conditions.

Current model trends bring the freezing drizzle in around 4 am, and have it exiting by 10 am or so.

Wednesday morning is likely to feature our next round of freezing rain chances.

Ice accumulations look to stay under 1/10", but it doesn't take much to lead to problems on the roads. Slick roads are possible, especially on those higher elevation surfaces. Bridges and overpasses are usually the first ones to freeze over, even if temperatures are not at or below-freezing.

We should warm above freezing by Wednesday afternoon, which should hopefully melt any ice that forms in time for the evening commute home.

Temperatures take a temporary nosedive into Thursday, as highs fall back into the lower 20s. We'll see plenty of sunshine Thursday, but clouds return by Friday morning.

The next system we'll be paying close attention to comes in Friday afternoon. Both the GFS and European models are in excellent agreement for this far out. By Friday afternoon, both models show snow developing. As a warmer air overspreads the region, this is likely to transition to a wintry mix Friday night. As conditions continue to warm, we may see a cold, yet non-frozen, rain by Saturday morning. It is far too early to have the exact details on snow totals, so continue to monitor the forecast.

European model brings snow into the Stateline by Friday afternoon.
The American model shows snow moving in late Friday evening.
